Eggcrate
 

Anyone know whether home depot sells eggcrate or not ?
Need to build a cover for my tank so that no fish can commit suicide.

Yes, but ask for the "light diffusers" or the Home Despot drone will stare blankly back at you.

ok thanks.
Cause I couldn't find it on their website.
But could find it at Rona's

Another option might be nylon mesh.

Did you make it yourself or bought a ready made ?

I haven't really made up my mind what I will get, whether use glass, acrylic, eggcrate or nylon mesh as you suggested.

My concern is whether it will reduce or block the light.

Not my tank but would be what I would use if I made a top.
IMO it would block less light than eggcrate.

What's the best way to cut the egg crate so it doesn't break?

I just use wire cutters and never had any crack on me. I also have a pair of flush cutting nippers that I prefer as it leaves no edge.

I would also suggest to look for some emergency screening as well, if you are trying to prevent gobies from jumping out of your tank. I have scissortail gobies and both managed to jump through the holes in the eggcrate. I was able to save one, who until I got the screening, had repeat suicide attempts, but the first one that jumped, did so when I wasn't home on a weekend.

Got a piece of eggcrate just now for temporary safety cover. Its clean looking but its blocking too much imo. Perhaps the silver would be better cause it will reflect the light.

When I have more time I will just make the top cover using the metal mesh.
